地基基礎抗震地震持續時間
  • duration : n. 1. 持久，持續。2. 持續時間，存在時間；期間。adj. -al
  • of : OF ＝Old French 古法語。
  • earthquake : n. 1. 地震。2. 大變動，動亂。
  1. The thesis discussed the effects of the factors on the high - rise isolated building, such as the rigidity and - damping of isolation system, the structural rigidity, the earthquake ground motion duration and so on

    本文對影響高層隔震建築的諸多因素如隔震系統的剛度、阻尼、結構的剛度、地震動持時、雙向地震作用等進行了討論，為工程建設提供一些參考。
  2. The duration aspect. in this part, strong motion duration ( trifunac - brady ) is studied, the main results are as follows : in general, for soil site, during strong earthquake, the 90 % relative energy duration increases with depth. the duration of the ground motion on surface is about 1 / 4 of that at depth of 100m

    三）地震動持時沿深度的變化規律摘要本文研究了地震動的90 %相對能量持時（ trifullac一brady ）得到如下結論:震級大小對于地震動持時沿深度的變化有一定影響，一般情況，震級越大地表的地震動持時與地下相比越小。
  3. Such question includes of what levels of the stress can be induced by different levels of shaking. failure criteria and the duration of time without failure of damaged column under the long - term loading are not confirmed. performance of damaged columns after repair will respond to a second or more earthquake attacks

    例如不同程度地震荷載對外包frp的影響，損傷柱在長期荷載作用下的破壞準則和工作時限， frp徐變對損傷柱殘余性能的影響，損傷柱的修復手段及抗震性能的恢復情況等。
